Zuo C, Fu Z, Lee EC, Foulke L, Young GQ, Cubero Rego D, Lee H. Microscopic ileitis in diverted and nondiverted enteric segments: an underrecognized condition with a multifactorial etiology. Hum Pathol 2018; 77:80-87. [PMID: 29596895 DOI: 10.1016/j.humpath.2018.03.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2018] [Revised: 03/07/2018] [Accepted: 03/19/2018] [Indexed: 02/07/2023]
Abstract
Microscopic ileitis has been infrequently reported in the literature with the few reported cases usually associated with concurrent microscopic colitis. Having encountered a case of collagenous ileitis involving the diverted distal limb of a loop ileostomy and sparing the proximal limb, we examined additional cases of loop ileostomy, end ileostomy, colostomy, and the accompanying diverted colorectal segment for features of microscopic ileitis and colitis. A total of 101 cases of diverted and nondiverted enteric segments were examined from 37 loop ileostomies, 16 end ileostomies, and 12 colostomies status post-Hartmann's procedure. The patients' clinical histories, including demographics and risk factors for microscopic colitis, were obtained from electronic medical records. The index case and an additional case showed collagenous ileitis: the former in the diverted distal limb, and the latter in the nondiverted proximal limb of the loop ileostomy. The latter was associated with high ileostomy output with watery diarrhea. Two additional cases showed lymphocytic ileitis: one in the nondiverted proximal limb of loop ileostomy and the other in the end ileostomy. All 4 patients had one or more risk factors for microscopic colitis. The etiology of microscopic ileitis seems to be multifactorial, and microscopic ileitis may be underdiagnosed. The diverted enteric segment may be involved by microscopic enteritis, suggesting that additional factors other than fecal stasis and altered bacterial flora may be contributing to its pathogenesis. When microscopic ileitis is encountered, identifying associated risk factors, recognizing incipient clinical symptoms of microscopic colitis, and considering other associated diseases or conditions are warranted.

Abstract
INTRODUCTION Microscopic colitis (MC) is a clinical syndrome of severe watery diarrhea with few or no endoscopic abnormalities. The incidence of MC is reported similar to that of other inflammatory bowel diseases. The need for histological confirmation of MC frequently guides reimbursement health policies. With the advent of high-definition (HD) coloscopes, the incidence of reporting distinct endoscopic findings in MC has risen. This has the potential to improve timely diagnosis and cost-effective MC management and diminish the workload and costs of busy modern endoscopy units. METHODS Publications on distinct endoscopic findings in MC available until March 31st, 2017 were searched systematically (electronic and manual) in PubMed database. The following search terms/descriptors were used: collagenous colitis (CC) OR lymphocytic colitis (LC) AND endoscopy, colonoscopy, findings, macroscopic, erythema, mucosa, vasculature, scars, lacerations, fractures. An additional search for MC AND perforation was made. RESULTS Eighty (n=80) articles, predominantly single case reports (n=49), were found. Overall, 1582 (1159F; 61.6±14.1 years) patients (pts) with MC and endoscopic findings were reported. The majority of articles (n=62) were on CC (pts 756; 77.5% females). We identified 16 papers comprising 779 pts (69.2% females) with LC and 7 articles describing 47 pts (72.3% females) diagnosed as MC. The youngest patient was 10 and the oldest a 97-year-old. Aside diarrhea, symptoms included abdominal pain, weight loss, bloating, flatulence, edema and others. In the study group we found 615 (38.8%) persons with macroscopic lesions in gut. Isolated linear ulcerations were identified in 7 pts (1.1%) while non-ulcerous lesions i.e. pseudomembranes, a variable degree of vasculature pruning & dwindling, mucosal lacerations and abnormalities such as erythema/edema/nodularity, or surface textural alteration in 608 pts (98.1%). The location of endoscopic findings was not reported in 27 articles. The distinct endoscopic findings were described in the left (descending, sigmoid, rectum - 10/21/11 studies), right (cecum, ascending - 7/7 studies), transverse colon (n=12), as well as duodenum (n=4), and terminal ileum (n=2). In 17 (1.1%) pts colonic perforation occurred. CONCLUSION Endoscopic findings are recognized with increased frequency in pts with MC. This could improve MC diagnosis by prompting a more extensive biopsy protocol in such cases and an earlier initiation of treatment. Procedure-related perforation has been reported in this group; therefore, cautious air insufflation is advisable when endoscopic findings are recognised.

Abstract
We report a unique case of systemic mastocytosis (SM) diagnosed in an ileal pouch biopsy obtained from a 44-year-old woman with ulcerative colitis. She presented with intermittent abdominal pain and watery diarrhea that did not respond to antibiotic therapy. The pouch biopsy showed expansion of the lamina propria by aggregates of CD117 and CD25-positive abnormal mast cells. A subsequent bone marrow analysis showed an increase in abnormal mast cells. Based on World Health Organization criteria, she was diagnosed with SM and responded to cromolyn sodium therapy. Systemic mastocytosis can mimic pouchitis, and thus recognition of this condition is important for appropriate clinical management.

Abstract
Microscopic colitis (MC) is the common denominator for lymphocytic and collagenous colitis (CC). It is now recognized as a relatively frequent cause of diarrhea that equals the prevalence of inflammatory bowel disease. Patients are typically middle-aged women, but disease may occur at every age. Patients with MC report watery, non-bloody diarrhea in the absence of endoscopic and radiologic abnormalities. Lymphocytic colitis is characterized by an increased number of intraepithelial lymphocytes, and CC by a thickened subepithelial collagen band, whereas in both an increased mononuclear infiltration of the lamina propria is found. The pathogenesis of MC is largely unknown, but may relate to autoimmunity, adverse reactions to drugs or (bacterial) toxins, and abnormal collagen metabolism in the case of CC. Budesonide is so far the only drug that has proven efficacy in randomized controlled trials both for the induction and maintenance of remission. Patients who are nonresponsive, dependent or who experience side effects on budesonide may benefit from thiopurine or anti-TNF treatment, but these options are still experimental. The long-term prognosis of MC is good; it does not appear to predispose to malignancies and can in some cases be self-limiting. Further research and randomized clinical trials are required to expand our understanding of the natural course and the pathogenesis of MC.

Abstract
Microscopic colitis includes the terms lymphocytic colitis and collagenous colitis, and is a common cause of chronic diarrhoea in older adults. The incidence of microscopic colitis has increased over time and has reached levels comparable to other forms of inflammatory bowel disease. In this chapter, an updated review on the epidemiology, diagnosis and treatment of microscopic colitis has been provided. There is limited data available about eosinophilic colitis, which is the least common of the eosinophilic GI disorders. It is important to rule out the secondary causes of colonic eosinophilia in patients with suspected eosinophilic colitis.

Abstract
Microscopic forms of colitis have been described, including collagenous colitis, a possibly heterogeneous disorder. Collagenous colitis most often appears to have an entirely benign clinical course that usually responds to limited treatment. Sometimes significant extracolonic disorders, especially arthritis, spondylitis, thyroiditis and skin disorders, such as pyoderma gangrenosum, dominate the clinical course and influence the treatment strategy. However, rare fatalities have been reported and several complications, some severe, have been attributed directly to the colitis. Toxic colitis and toxic megacolon may develop. Concomitant gastric and small intestinal inflammatory disorders have been described including celiac disease and more extensive collagenous inflammatory disease. Colonic ulceration has been associated with the use of nonsteroidal anti-inflammatory drugs, while other forms of inflammatory bowel disease, including ulcerative colitis and Crohn disease, may evolve directly from collagenous colitis. Submucosal 'dissection', colonic fractures, or mucosal tears and perforation, possibly from air insufflation during colonoscopy, have been reported. Similar changes may result from increased intraluminal pressures that may occur during radiological imaging of the colon. Neoplastic disorders of the colon may also occur during the course of collagenous colitis, including colon carcinoma and neuroendocrine tumours (ie, carcinoids). Finally, lymphoproliferative disease has been reported.

Abstract
BACKGROUND Refractory microscopic colitis is a rare condition with an unknown rate of occurrence. The efficacy of anti-tumor necrosis factor (TNF) therapy for microscopic colitis has never been reported. Aims 1) To report the frequency of refractory microscopic colitis in the database of the participant hospitals. 2) To describe the therapeutic response to anti-TNF therapy among the refractory cases. METHODS Patients with a histological diagnosis of collagenous colitis and lymphocytic colitis were identified through the Department of Pathology database and the IBD practice database. Patients refractory to medical treatment and with severe symptoms were offered anti-TNF therapy. RESULTS Five of 372 MC patients (1.3%; 95% CI, 0.6 to 3.1) presented with severe symptoms refractory to standard medical therapies. One patient was denied therapy from her insurance carrier. The other 4 received infliximab therapy. The response was excellent after one dose experiencing a 60-90% decrease in bowel movements. Three patients were switched to adalimumab (2 allergic reactions and 1 early loss of response to infliximab). Long-term clinical remission (more than 1 year) was achieved in three cases (2 with adalimumab and 1 with infliximab). One patient on adalimumab had an early loss of response and was referred for colectomy. CONCLUSIONS Microscopic colitis with severe symptoms refractory to standard medical therapy including immunosuppressives is uncommon. In this setting, anti-TNF therapies may be a good option to avoid colectomy.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the surgical treatment of choice for patients with medically refractory ulcerative colitis (UC) or UC with dysplasia and for the majority of patients with familial adenomatous polyposis. However, UC patients with IPAA are susceptible to inflammatory and noninflammatory sequelae, such as pouchitis, Crohn's disease of the pouch, cuffitis, and irritable pouch syndrome, in addition to common surgery-associated complications, which adversely affect the surgical outcome and compromise health-related quality of life. Pouchitis is the most frequent long-term complication of IPAA in patients with UC, with a cumulative prevalence of up to 50%. Pouchitis may be classified based on the etiology into idiopathic and secondary types, and the management is often different. Pouchoscopy is the most important tool for the diagnosis and differential diagnosis in patients with pouch dysfunction. Antibiotic therapy is the mainstay of treatment for active pouchitis. Some patients may develop dependency on antibiotics, requiring long-term maintenance therapy. Although management of antibiotic-dependent or antibiotic-refractory pouchitis has been challenging, secondary etiology for pouchitis should be evaluated and modified, if possible.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for the majority of patients with medically refractory ulcerative colitis (UC) or UC with dysplasia, or familial adenomatous polyposis. Various forms of pouchitis frequently occur after surgery. In fact, pouchitis is the most frequent long-term complication of IPAA in patients with UC, with a cumulative prevalence of up to 50%. The etiology and pathogenesis of pouchitis are not entirely clear. It is generally believed that the initiation and development of the disease process of pouchitis is associated with dysbiosis of pouch reservoir, as evidenced by a favorable response to antibiotic therapy. However, the majority of the patients do not show identifiable etiopathogenetic or triggering factors, therefore being labeled to have idiopathic pouchitis. In contrast, a subgroup of patients, particularly those with antibiotic-refractory pouchitis, may have obvious triggering factors for disease flare-up and progression and may be considered to have secondary pouchitis. Therefore, pouchitis can be classified on the basis of etiology into idiopathic and secondary causes. Approximately 20-30% of patients who present with chronic pouchitis have secondary identifiable and triggering factors, including cytomegalovirus or Clostridium difficile infection, ischemia, concurrent immune-mediated disorders, radiation, collagen deposition, and use of nonsteroidal anti-inflammatory drugs. Careful evaluation of these secondary causes of pouchitis that may contribute to resistance to antibiotics should be performed before the introduction of next-line medical therapy.

Abstract
When surgery is necessary in patients with ulcerative colitis, total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the procedure of choice. Several inflammatory and noninflammatory complications can occur after IPAA. Pouchitis is the most common, occurring in approximately 50% of patients. Whereas "acute" pouchitis can be treated rapidly and successfully in the majority of patients, "refractory" and "chronic pouchitis" remain therapeutic challenges to patients and physicians. This article reviews the literature and offers consensus guidelines on issues related to the epidemiology, diagnosis, pathogenesis, risk factors, and treatment of pouchitis.

Abstract
While the overall incidence of pouchitis is low, extensive research continues at clinical and experimental levels in attempts to unravel its etiology. The ileal pouch and pouchitis together represent a unique in vivo opportunity to study mucosal adaptation and inflammation in depth. In the recent past, molecular data relating to pouchitis has significantly expanded. These data provide invaluable insight into intracellular and extracellular events that underpin mucosal adaptation and inflammation. Advances in classification, risk factor evaluation, and prevention have meant that a review of this data, as well as its relationship to our current understanding of pouchitis, is both timely and warranted. Therefore, the aim of this review is to summarize recent data in the context of the established literature.

Abstract
BACKGROUND Collagenous colitis is a cause of chronic diarrhea. Treatment has been based mainly on anecdotal evidence. This review was performed to identify therapies for collagenous colitis that have been proven in randomized trials. OBJECTIVES To determine effective treatments for patients with collagenous colitis. SEARCH STRATEGY Relevant papers published between 1970 and December 2007 were identified via the MEDLINE and PUBMED databases. Manual searches from the references of identified papers, as well as review papers on collagenous or microscopic colitis were performed to identify additional studies. Abstracts from major gastroenterological meetings were searched to identify research submitted in abstract form only. Finally, the Cochrane Controlled Trials Register and the Cochrane Inflammatory Bowel Disease and Functional Bowel Disorders Group Specialized Trials Register were searched for other studies. SELECTION CRITERIA Ten randomized trials were identified. Seven of these compared active treatment to placebo for treating active disease. Of these, 1 trial studied bismuth subsalicylate, 1 trial studied Boswellia serrata extract, 3 trials studies budesonide, 1 trial studied prednisolone, and 1 trial studied probiotics. One trial compared mesalamine to mesalamine + cholestyramine for treating active disease. Two trials compared budesonide to placebo in maintaining response induced by budesonide. DATA COLLECTION AND ANALYSIS Data were extracted independently by each author onto 2x2 tables (treatment versus comparator and response versus no response). For therapies assessed in one trial only, P-values were derived using the chi-square test. For therapies assessed in more than one trial, summary test statistics were derived using the Peto odds ratio and 95% confidence intervals. Data were combined for analysis only if the outcomes were sufficiently similar in definition. MAIN RESULTS In treating active disease, there were 9 patients with collagenous colitis in the trial studying bismuth subsalicylate (nine 262 mg tablets daily for 8 weeks). Clinical response occurred in 100% of patients who received bismuth subsalicylate compared to 0% of patients who received placebo (P = 0.03). Thirty-one patients were enrolled in the trial studying Boswellia serrata extract (three 400 mg capsules daily for 8 weeks). Clinical response occurred in 44% of patients who received Boswellia serrata extract compared to 27% of patients who received placebo (P = 0.32). A total of 94 patients were enrolled in 3 trials studying budesonide (9 mg daily or in a tapering schedule for 6 to 8 weeks). Clinical response occurred in 81% of patients who received budesonide compared to 17% of patients who received placebo (P < 0.00001). The pooled odds ratio for clinical response to treatment with budesonide was 12.32 (95% CI 5.53 to 27.46), with a number needed to treat of 2 patients. Statistically significant histological response occurred with treatment in all 3 trials studying budesonide therapy. Eleven patients were enrolled in the trial studying prednisolone (50 mg daily for 2 weeks). Clinical response occurred in 63% of patients who received prednisolone compared to 0% who received placebo (P = 0.15). Twenty-nine patients were enrolled in the trial studying probiotics (2 capsules containing 0.5 x 10(10) CFU each of L. acidophilus LA-5 and B. animalis subsp. lactis strain BB-12 twice daily for 12 weeks). Clinical response occurred in 29% of patients who received probiotics compared to 13% of patients who received placebo (P = 0.38). Twenty-three patients were enrolled in the trial studying mesalamine (800 mg three times daily) with or without cholestyramine (4 g daily) for 6 months. Clinical response occurred in 73% of patients who received mesalamine alone compared to 100% of patients who received mesalamine + cholestyramine (P = 0.14). In maintaining response, 80 patients who had responded to open-label budesonide were enrolled in 2 trials studying budesonide (6 mg daily for 6 months). Clinical response was maintained in 83% of patients who received budesonide compared to 28% of patients who received placebo (P = 0.0002). The pooled odds ratio for maintenance of clinical response to treatment with budesonide was 8.40 (95% CI 2.73 to 25.81), with a number needed to treat of 2 patients. Histological response was maintained in 48% of patients who received budesonide compared to 15% of patients who received placebo (P = 0.002). AUTHORS' CONCLUSIONS Budesonide is effective for inducing and maintaining clinical and histological response in patients with collagenous colitis. The evidence for benefit with bismuth subsalicylate and for mesalamine with or without cholestyramine is weak. There is no evidence for the effectiveness of Boswellia serrata extract, prednisolone, or probiotics. These agents and other therapies require further study.

Abstract
Microscopic forms of colitis have been described, including collagenous colitis. This disorder generally has an apparently benign clinical course. However, a number of gastric and intestinal complications, possibly coincidental, may develop with collagenous colitis. Distinctive inflammatory disorders of the gastric mucosa have been described, including lymphocytic gastritis and collagenous gastritis. Celiac disease and collagenous sprue (or collagenous enteritis) may occur. Colonic ulceration has been associated with use of nonsteroidal anti-inflammatory drugs, while other forms of inflammatory bowel disease, including ulcerative colitis and Crohn’s disease, may evolve from collagenous colitis. Submucosal “dissection”, colonic fractures or mucosal tears and perforation from air insufflation during colonoscopy may occur and has been hypothesized to be due to compromise of the colonic wall from submucosal collagen deposition. Similar changes may result from increased intraluminal pressure during barium enema contrast studies. Finally, malignant disorders have also been reported, including carcinoma and lymphoproliferative disease.

Abstract
Both medical and surgical therapies for ulcerative colitis have inherent advantages and disadvantages that must be balanced for patients with moderate to severe disease. Restorative proctocolectomy with ileal pouch-anal anastomosis has become the surgical treatment of choice for the majority of patients with ulcerative colitis who require proctocolectomy. However, adverse sequelae of mechanical, inflammatory, functional, neoplastic, and metabolic conditions related to the pouch can occur postoperatively. Recognition and familiarization of the disease conditions related to the ileal pouch can be challenging for practicing gastroenterologists. Accurate diagnosis and classification of the disease conditions are imperative for proper management and prognosis.

Abstract
PURPOSE Management of chronic refractory pouchitis, a common cause for pouch failure with pouch resection or diversion, is often challenging. The aim of this study was to assess the efficacy and safety of a combination therapy of ciprofloxacin and tinidazole in patients with chronic refractory pouchitis compared with mesalamine therapy. METHODS Sixteen consecutive ulcerative colitis patients with chronic refractory pouchitis (disease>4 weeks and failure to respond to>4 weeks of single-antibiotic therapy) were treated with a four-week course of ciprofloxacin 1 g/day and tinidazole 15 mg/kg/day. A historic cohort of ten consecutive patients with chronic refractory pouchitis treated with oral (4 g/day), enema (8 g/day), or suppository (1 g/day) mesalamine served as controls. The Pouchitis Disease Activity Index, clinical remission, clinical response, the Cleveland Global Quality of Life, the Irritable Bowel Syndrome-Quality of Life, and the Short Inflammatory Bowel Disease Questionnaires scores were calculated before and after therapy and compared between the two treatment groups. RESULTS Patients taking ciprofloxacin and tinidazole had a significant reduction in the total Pouchitis Disease Activity Index scores and subscores and a significant improvement in quality-of-life scores (P < 0.002). For patients in the mesalamine group, there was a significant reduction in the total Pouchitis Disease Activity Index scores only. Patients in the antibiotic group had a greater reduction in the total Pouchitis Disease Activity Index scores and a greater improvement in the quality-of-life scores than those in the mesalamine group (P <or= 0.03). The rate of clinical remission and clinical response for the antibiotic group was 87.5 percent and 87.5 percent, respectively, and for the mesalamine group it was 50 percent and 50 percent, respectively (P = 0.069). Two patients in the antibiotic group (peripheral neuropathy and dysgeusia) developed adverse effects. CONCLUSIONS Combination therapy with ciprofloxacin and tinidazole was generally well tolerated and was effective in treating patients with chronic refractory pouchitis.
